More Triassic Mercia mudstone slabs descovered containing fossil sand ripples.

  1 - I can find no reference to other finds like these in the rare Mercia mudstone exposures of the Cleveland area. 
  2 - I have informed Geological groups, but still await a reply.

  9 - There is a possibility that these cracks contain some type of fossils, i.e. there are some very strange and intricate shapes in there.

Stone tool & Preseved leather

 1 This preserved leather was found by myself at a location on the banks of the river Leven, on the boarder of Cleveland and North Yorkshire.

 2 - It has the same appearance and needle marks as previous preserved material I have found, in all of the deep beck valleys of south west Cleveland.  HISTORY OF A BECK: Preserved leather

 3 - As ive stated before I have no idea of the age of these pieces of preserved leather, but i am sure all are hand made and had ornamental stitching attached.

 4 - Note the polished finish on the leather.

 5 - This slate has been shaped and had a hole bored into it, again I have no idea of its age, I can only imagine it as some kind of fishing tool ?

 6 - Note the wear marks toward the right as viewed.

 7

 8 - The tool was found close to the leather although this in no way links them i.e. the leather could have travelled far, the stone probably not far.

Trassic sand ripples descovered River Leven

I decided to go back to the river  Leven on the boarder of Cleveland and North Yorkshire today to try and discover where the sand ripple fossil my daughters had found earlier had come from.

1 The red outline marks the preserved Triassic sand ripples

 2 The white outline shows one of the preserved Triassic sand ripple sections.

 6 The sand ripple fossils seem to run in a west to east direction although I can not be totally sure, as I had no compass.

 7 - The river has cut through the sand ripple layer many years ago but slabs can still be found in the river.

 8 - The black outline shows the sand ripples exposed from the upper Triassic deposits, at least 5 metres in depth.

 

 9 The yellow outline shows the excavated  sand ripples to the left.

Fossil triassic sand ripples

My Daughters found these pieces at the weekend, ime sure there Triassic sand ripples.

 7 - The larger piece has been discoloured by the river and weathering, and may even have a secondary mineral coating,  but after breaking an under layer free I can say it is certainly Mercia mudstone.
 
 
 8 - The examples  in images 8 - 10 show Triassic fossil sand ripple marks from North America, I have not yet viewed a Triassic example from the UK.

 11- This image shows how the earth looked at the approximate time the sand ripples were made.
